hcg vs gonadorelin
updated
hcg (tier S) vs gonadorelin (tier C): what each is, why each got its grade, half-life and source counts side by side.
hcg · tier S
A placental glycoprotein hormone that activates the LH receptor. Product form and labeled route matter.
tier rationale
Current labels and a deep fertility record support the established clinical lane. The testosterone-adjunct question has smaller human studies, and the diet claim fails controlled review.
gonadorelin · tier C
Native-sequence GnRH with real historical pump and diagnostic uses. Pulse timing determines whether the signal works.
tier rationale
Human efficacy is real when gonadorelin is delivered as a physiologic pulse. The common TRT substitution claim uses a different schedule and lacks a controlled outcome trial.
